According to Emissions Division Director Dasun Janaka Gamage, around 1,000 vehicles suspected of releasing excessive black smoke have been inspected so far in 2026.
He said inspections have been intensified across 12 districts with high vehicle density, with mobile inspection teams also deployed to strengthen enforcement efforts.
Vehicle owners whose vehicles are found to be emitting excessive black smoke are given a 14-day period to rectify the defects.
The Emissions Division warned that legal action will be taken against owners who fail to comply within the given timeframe, and such vehicles will be blacklisted.
The programme is being carried out under the supervision of the Department of Motor Transport to reduce vehicular emissions and improve air quality.
